Detailed Review
History and Ownership
Monsam Enterprises Inc. was founded in 1998 and remained a small manufacturing operation until it was acquired by Ray and Dana Chery through an entrepreneurship-through-acquisition process, as detailed in a 2024 McKinsey article. The couple, both Tufts University alumni, took over the business and have continued its focus on mobile hygiene solutions. A January 2025 blog post announced a refreshed logo and website, noting the company had been in operation for 27 years, consistent with the 1998 founding date.
Business Model and Products
The company generates revenue by designing, manufacturing, and selling portable sinks and related equipment directly to end users and through distributors. Its product line includes portable handwashing stations, mobile concession carts, mobile kitchen workstations, scientific lab sinks, cosmetology shampoo sinks, and child-height units. Each unit is self-contained with freshwater and wastewater tanks and electric water heating. Customers can also request fully custom units tailored to specific space, color, and functional requirements.
Market Position and Customers
Monsam occupies a niche in the commercial hygiene equipment sector, competing with other portable sink manufacturers but differentiating through its extensive customization options, NSF and ADA certifications, and broad range of models. The company has served over 11,000 customers, including schools, event organizers, healthcare facilities, and foodservice operators. Despite its small headcount, it ships across the United States and Canada and offers international consultation.
Leadership and Structure
The company is privately held with a lean management structure. Ray Chery serves as CEO and is the only C-level executive publicly identified. Dana Chery is a co-owner but does not hold a confirmed C-level title. The company does not list a full executive team on its website or LinkedIn, and no other C-level roles were found in available sources.
